Most of our orders are from repeat customers. Parts-People began as a small company 20 years ago in an extra bedroom of my house. I had saved a small sum of money to purchase some computer parts and began selling them on eBay. After a few months I realized that people needed a place to go for Dell parts so I began building our website. Since we are located in Austin, Texas, where Dell.com was founded, I was able to set up a solid supply line with Dell. From the start, we focused on customer satisfaction and selling quality parts. We have grown a lot since 2002 but still and always the customer will come first. You will find that we go above and beyond with every order and offer free resources and support before and after the sale.

When a laptop or computer first powers on, it goes through an initial set of diagnostic tests to make sure vital components are preforming correctly. These tests are called POST or Power On Self Test. When a test fails, the user is notified via POST codes, Light codes, or Beep codes. For diagnosing Beep codes you need to:
Power on the laptop or restart it if it is already on.
Listen to the number of consecutive beep when the computer begins to boot. Restarting the laptop may be necessary and should not harm the laptop at this time.
